Figure 2From: Mesenchymal stem cell spheroids exhibit enhanced in-vitro and in-vivo osteoregenerative potentialEffect of seeding densities on a spheroid formation. (A) Representative images of mesenchymal stem cell (MSC) spheroids grown on low-binding plates at 24 h after implantation. Scale bar = 100 μm. (B) The diameter of MSC spheroids increased linearly with increasing cell number.Back to article page
